to provide in such a device improved means for irrevolubly uniting a nutand its bolt.

In the accompanying drawings, Figure I is a side elevation of a bolt andnut embodying I .one form of our invention, partially in section,showing in section an object to which it is applied. Fig. II is asimilar view showing a modified form of embodiment of our invention.'Fig. III is a side elevation of such a nut as is shown in Fig. IIapplied to a slightly-modified form of bolt. Fig. IV is a top plan viewof the bolt and nut shown. in

. Fig. I detached. Fig. V is a bottom plan view of the .nut shown inFig. II detached. Fig. VI is a top plan view of the subject-matter ofFig. III. Fig.VII is a perspective view of a washer adapted to fit sucha bolt as is shown in Figs. I and II. Fig. VIII is a lan view. of aWasher ada ted to fit a bolt 0 the shape shown in Fig. I I.

Referring to the numerals on the drawings, 1 indicates a bolt, 2 thehead thereof, and 3 a nut threaded to fit the threaded end 4 of thebolt. 5indicates, bywayof exam 1e, an 3 5 object through which the boltis passe Our invention being comprehended in the class of base-washernut-locks includes as a member any suitable form of washer 7-such, forexample, as that shown in Fig. VII. The washer is free to travellengthwise of the threaded portion of the bolt, but is irrevolubly fixedthereto in order that when the nut is advanced to the required positionupon the bolt it may be secured in that position by se- 4 5 curing it tothe washer. To that end the bolt may be provided with a longitudinalchannel 8 and the washer with alug 9, loosely fitting said channel.Instead of the channel -81 and lug 9 the threads of the bolt may bemutilated bya flat side 10, and the bore 11 of thelwasher ma becorrespondingly shaped, as shown in F ig.. III.

As a means of securing the nut to the washer We prefer to make thewasher of metal of suflicient flexibility to permit of its being bent asrequired, and upon it we rovide at suitable intervals and availablydisposed a series of tongues 15, 16, 17, and 18. Preferring to make thewasher disk-shaped, each tongue may be defined by a pair of parallelkerfs 19. By this arrangement the washer is made and kept perfectlysmooth and un obstructive until it is bent to perform its function.

To adapt the nut to receive the tongue for fastening it in position, thenut may be rovided upon its bottom with a plurality o radial ordiametrical channels 20, each radial channel having its bottom definedby a face 21', upwardly inclined from the bore 220i the nut outwardly.mpareFigs. II, III, and V.) The shape of the channels 20 facilitates thebending of a selected tongue into a se-v lected channel through theemployment of a suitable instrument, which for thepur ose may beinserted between the tongue an the object against which the washer liesin practice. The shape also facilitates the driving back of an engagingtongue to liberate the nut when desired.

Instead of channels formed upon the base of the nut, as above described,the nut may be provided with a circular base-flange 23, provided at freuent intervals with radial channels or ngtdlies 24, as shown in Figs. Iand IV. A tongue of the Washer being exposed through a notch 24 may be.bent up into an engaging position, as shown. in Fig. I, or driven downout of engagement for the liberation of the nut, as required.

What We claim is 1. The combination with a bolt and its nut of adisk-sha ed washer, provided with a plurality of racial tongues, eachtongue being defined by a pair of parallel kerfs, radial channels uponthe nut adapted to receive into close-fitting engagement any one ofsaid' tongues when deflected into it and means for .opefiativelysecuringthe washer and bolt toet er. i g 2. The combination with a bolt and itsnut of a disk-sha ed Washer, provided with a plurality of ra ialtongues, each tongue being defined by a pair of parallel kerfs. radialchannels upon the nut adapted to receive ihte close-fitting engagementany one of sehl "tongues when deflected into 1'1), ee'eh ef saidchannels being formed in the bottom of the nutencl each having itsbottom defined by a fee upwardly inclined from the bore 01" the nutoutwardly, and. means for opel'etively securing thewe'eher and belttogether.
